Device Data

API v3
Last updated May 2021

The card issuer uses Device Data Collection (DDC) to fingerprint the customer's device.

Along with the risk data in theauthenticationrequest, it's used to decide if achallengeis needed or if the authentication can be frictionless (no challenge displayed to the customer). This step is required for the authentication to use 3DS2.

Important: Invoke this process immediately upon the customer providing their payment credentials. This ensures that device data collection processes asynchronously behind the scenes as the customer completes the remaining checkout process. If a customer changes their card number after the device data collection process is started or completed, re-execute the entire DDC process

Device data initialization

POST your device data initialization request to the 3ds:deviceDataInitialize action link.

This request creates a JSON Web Token (JWT) that is used as part of the Device Data Collection (DDC) form. The DDC form also requires the first six digits of your customer's card number (BIN). The BIN can be returned if a token resource is provided, see JWT + BIN (token) request.

For consistency of integration you can also provide the full card number JWT + BIN (card). It will be truncated to become the BIN in the response.

ParameterMandatoryDescription
transactionReferenceA unique reference for authentication. For example, e-commerce order code.
Use the same transactionReference across all 3 potential request types (deviceDataInitialization, authentication, verification).
merchant.entityUsed to route the request in Access Worldpay, created as part of on-boarding.
paymentInstrument.typeAn identifier for the paymentInstrument being used.

type : card/fronttype : card/tokenized

Device data initialization response

Best Practice: Access Worldpay returns a WP-CorrelationId in the headers of service responses. We highly recommend you log this. The WP-CorrelationId is used by us to examine individual service requests.

ParameterDescription
deviceDataCollection.jwtA digitally signed token that contains additional details required for DDC.
Expires in 10 minutes for both Try and Production.
deviceDataCollection.urlA POST action on the DDC form. Used to redirect to the issuers DDC page.
deviceDataCollection.binFirst six digits of the card number (Bank Identification Number), used as part of DDC. Returned if a token resource or card number is included in the request.

Note: In case of an error, you can get further information in ourerror reference.

Device Data Collection (DDC)

Once you have the JWT, URL and BIN you can create and submit the DDC form.

A SessionId representing this collection is then used as part of the risk analysis by the issuer in theauthentication request.

Device Data Collection form

Here's an example of how you would set-up the DDC form in an iframe.

  1. Create a hidden iframe and set the src attribute with the URL of the page that will POST the DDC form. This URL should contain in query string parameters the deviceDataCollection.jwt, deviceDataCollection.bin and deviceDataCollection.url as those will be used in the DDC form.

    <iframe height="1" width="1" style="display: none;" src="replace-this-with-the-url-of-your-page-that-posts-the-ddc-form"></iframe>
  2. Create and host the page that POSTs the DDC form.

Device Data Collection postMessage

Once the DDC form is submitted and is successfully sent to the card issuer, you are notified via apostMessageevent.

For security, verify the sender's identity using the postMessage origin property as detailedhere.

An example postMessage response:

{
  "MessageType": "profile.completed",
  "SessionId": "0_3XXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXX6b5",
  "Status": true
}
KeyValue
messageTypeprofile.completed
SessionIdUUID, not present or undefined
Status
  • true - Use the SessionId value in deviceData.collectionReference as part of theAuthentication request
  • false - SessionId is empty. Either retry DDC or send the authentication request without the deviceData.collectionReference. This downgrades the authentication to 3DS1.

The DDC call typically takes 1-2 seconds, depending on the latency between the customer's device, the Cardinal servers and, in part, the type of device data collection performed by the different issuers. The 3DS specification has the maximum response time at 10 seconds.

Note: If no postMessage is provided either retry DDC or send theAuthentication requestwithout the deviceData.collectionReference. This downgrades the authentication to 3DS1.
